| Verizon | 6609 Western Run Dr | Impossible to get data connection, and bad call signal | 2014 | 
| AT&T | 799 Hollow Rd | absolutely no service anywhere near my house or in my house. This whole hill has zero service. | 2019 | 
| Verizon | 8108 Harford Rd | I have no cellular service in my home in Parkville, MD 21234 | 2015 | 
| AT&T | 2445 Forest Green Rd | Terrible and weak reception, for over 2 years. With LTE enabled on iphone, the average signal strength is -115 to -130 db making the phone completely useless and unable to make calls.. With LTE disabled, the signal reception improves to an average of -95 to -105db, enabling the making and receiving of phone calls, but the call quality is so poor that I often have to go outside to have conversations, as people cannot hear me indoors. Importantly, ATT has only tower within a 4-mil radius of my location, while T-Mobile, Verizon and Sprint have well over 20.If you live in the Baltimore area, particularly not in the middle of downtown, I would strongly recommend you use any other carrier than AT7T, unless you like going outside every time you want to make a call. | 2014 | 
| Verizon | 821 W Benfield Rd | Extremely poor service in this area with all carriers | 2014 |
